The utterance of a squealing, gasping, or other related high-pitched or fangirly noise in reaction to something utterly and undeniably cute and adorable. It is often uncontrollable and unintended, causing much embarrassment in the instance of a cutegasm in a public place. The noises closely resemble that of an actual orgasm to those unaware of the cause.

Leah cutegasmed noisily at the picture of the adorable gray kitten. Since she was in the library at the time, she was given some rather dubious looks by people standing nearby.
